摘　　要：分析了凹侧形可伸缩带式输送机在空载、满载、下运段满载、下运段空载4种工况下运行时输送带张力分布及变化规律,提出了解决这种特殊侧形输送机出现问题的方法。实践证明,采用安装阻尼板、减小过渡段托辊间距、运量控制、提高张紧力和改变张紧装置工作模式、延长停机时间等方法,有效解决了输送机出现的负功率运行、叠带、倒架、掉托辊等事故。Analyzes the concave side-telescopic belt conveyors at idle and under full load, transport loaded with four kinds of condition, under paragraph no-load belt tension distribution and variation at run time, puts this particular profile conveyor problems of method. Practice has proved that the installation plate, reducing the transitional distance between rollers, volume control, increased tension and change the take-up method of working mode, extended downtime, effectively resolve negative power conveyor running, stacks, racks, rollers and other accidents.
